THOMAS A. OOOPERRIDER, OF THORNVILLE, OHIO.

WELL-CAP.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed January 20,1906. Serial No. 297,018.

To all whmn it may concern.-

Be it known that I, THOMAS A. COOPER- RIDER, a citizen of the United States, residing at Thornville, in the county of Perry and State of Ohio, have invented a new and useful lVelhOap, of which the following is a specification.

This invention relates to a device designed for use with board-wells constructed either with or without a well-pit.

The object of the invention is to exclude dirt, and especially surface water or drainage, from the well-pipes.

The invention consists of the novel features of construction hereinafter set forth, pointed out in the claims, and shown in the accompanying drawings, in which Figure 1 is a side elevation showing the aplioation of my device to a pump, parts being broken out and shown in section. Fig. 2 is a detail sectional view of the cap comprising a cover and casing bolted together. Fig. 3 is a plan view of the casing.

In the drawings, A represents a pump mounted upon a suitable base A, which base rests upon a cover A extending over the well-pit.

My cap consists of a concaved cover or top B, which is centrally perforated and thread ed, and a short pipe-section B is threaded into the said perforation and connects at its upper end with a pump-pipe B, and at its lower end with a well-pipe B Sleeves B are arranged, respectively, above and below the top B and close the joints between the pipes B and the pipes B and B.

A barrel O incloses the well-pipe B and terminates a slight distance below the top B. A casing D is split lengthwise, as shown at D, and is provided with two pairs of lugs, as shown at D and its upper portion is flared outwardly to form a bell-mouth D lVithin the casing and immediately below the bellmouth D is an annular downwardly-curving shoulder E.

In use the barrel O extends upwardly withshoulder and the inner face of the casing.

The bell-mouth of the casing rests against the under face of the rim of the top B and is bolted to the same. The casing is-locked in position upon the barrel O by bolts and nuts, the bolts working through the lugs D In case the well is not provided with a well-pit the cover (shown at A in Fig. 1) serves as the top, and the casing D is bolted to said cover, as shown in dotted lines in Fig. 1, or the cover A is dispensed with and the top B substituted therefor, as the two are practically the same in construction. Packing material of any kind may be placed between the cap B and the casing D.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a pump-pipe, of a concaved top, a barrel terminating short of said top, a casing having a bell-mouth adapted to lit against the top, the said casing inclosing the upper portion of the barrel, and a shoulder within the casing, curving downwardly and adapted to bear upon and overlap the upper edge of the barrel.

2. The combination with a pumpbarrel, of a casing split lengthwise from its lower end,

a bell-mouth being formed at the upper end,

an annular inwardly and downwardly curving shoulder formed in the casing between the bell-mouth and the inner end of the slot, and adapted to bear upon and overlap the upper edge of the barrel, and a top adapted to fit over the said casing.

3. A device of the kind described comprising a casing split longitudinally from its lower end, an interior downwardly-curving shoulder formed immediately above the inner end of the said slot, a bell-mouth formed on the casing above the said shoulder, a top having a central threaded perforation said top resting upon the bell-mouth, lugs carried by the casing adjacent the slot, and means for drawing the edges of said slot toward each other.
